| Write function | Description |
|---|---|
| Write (2) | Single-phase write writing of objects (with a returned numeric code confirming successful write or specifying a write error). |
| Select (3) + Operate (4) | Two-phase write of objects that virtually excludes the possibility of error due to undetected interference on the line. |
| Direct Operate (5) | Single-phase write of objects. It returns a group, index, and write value in addition to the return code. |
Direct Operate Non Return (6) | Single-phase write of an object without acknowledgment (the least secure but with the least load on the communication medium). |
